The Omron CQM1-AD042A Analog Input Module is a plug-in I/O card for the Omron CQM1 Programmable Logic Controller, extending the system with analog input capability. Identified as CQM1-AD042A (also listed as CQM1AD042A), it provides the analog input interface the CQM1 PLC uses to read signals and feed data to the CPU. As part of the CQM1 family, this module mounts on the backplane and integrates with the controller to support real-time data acquisition and control tasks.
